ABSTRACT

A teleprinter apparatus for typeing or tape punching Roman alphabet characters, numbers, and symbols, and Chinese characters includes a platen and means for spacing and rotating the platen and operating the tape punching means. Code unit receiving means is provided for receiving multi-element code units representing characters, symbols, numbers and functions to be carried out by the apparatus, and the apparatus has a plurality of function means responsive to receipt of function code units for driving the apparatus for carrying out the functions represented by the function code units. Conversion function means is provided which is responsive to the receipt of conversion function code units for converting the apparatus from a normal operational state in which it prints Roman characters, numbers and symbols to a Chinese character operational state in which it prints Chinese characters and vice versa. One of said function means is spacing function means for driving the platen spacing means for every two code units received by said code unit receiving means, and this spacing function means is coupled to the conversion function means for actuation when the apparatus is in the Chinese character operational state. The apparatus has printing means for printing characters, symbols and numbers on the platen, and transmission means are coupled to the code unit receiving means for receiving single code units and when they are for characters, numbers and symbols to be printed, transmitting them, further transmission means are coupled to the code unit receiving means for receiving code units corresponding to characters, numbers and symbols, storing them and then transmitting them when the apparatus is in the normal operation state and when the apparatus is in the Chinese character operational state transmitting the second code unit of each pair directly to the printing means. One of said function means is normal printing function means coupled to the further transmission means for causing the further transmission means to store the code unit and transmit it to the printing means. One of said function means is Chinese character printing function means coupled to the further transmission means for coupling the further transmission means directly to the printing means, and one of the function means is tape punching function means for coupling the respective transmission means to the tape punching means.
